IMPROVEMENTIN VENTILATORS FOR RAILROAD-CARS.

Specification forming part of Letters Patent No. 33,565, dated October29, 1861.

To all whom it may concern:

Be it known that I, LESTER C. BEARDsLEY, of Cleveland, county ofCuyahoga, and State of Ohio, have invented a new and Improved Ventilatorto be Used for the Purpose of Ventilating Passenger-Gars on Railroads;and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,and t-o the letters of reference marked thereon, like letters referringto like parts.

The nature of my invention consists in the construction of a ventilatorby the use of which the foul and impure air may be expelled from theinside of the car, and pure fresh air may by the saine ventilator beinjected into the car at the will of the passengers, or of those havingcharge or control of the train, aventilator so constructed that it mightbe used for the double purpose of ejecting the foul or injecting purefresh air into the car, and to be operated in either way without anyregard as to which direction the car is moving or which end of the caris foremost, and to be readily and easily applied to the car with littleexpense.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I construct my ventilator substantially as represented in theperspective view, Figure l, of galvanized iron.

I, Fig. l, is the reservoir.

G, Fig. l, is a cover to an opening of the reservoir.

K, Figs. l, 2, and 3, is a reversible funnelshaped air injector orejector.

H, Figs. l, 2, and 3,'is a tube throughwhieh the air passes as it isinjected or ejected from the reservoir.

L, Figs. l and 2, is a tube through which the air passes as it escapesfrom the reservoir to the car, or from the car to the outside into theopen air.

S, Figs. l and 2, is a faucet, which is used to draw the Water, asrepresented at N N, Figs. l and 2, from the reservoir.

ct a, Fig. 1, represents a shoulder formed on tube H. This tube passesthrough the cover or top of the reservoir and down into the perforatedplate J, Fig. 4, through holes b b b b, as represented at J, Fig. 2. Theperforated plate J is secured to the inside of the reservoir in theposition as represented in Figs. 2 and 3 by being soldered. Tube H issecured to the reservoir by means of a small washer that is secured tothe tube I-I at Y Y, Figs. 2 and 3.

On the inside of the reservoir a tube P, Figs. 2, 3, and 4, is secured,and into tube P rod O is inserted. This rod is secured to tube H, asrepresented at R R, Figs. 2 and 3, by a bolt and screws c c, Fig. 3. Onthe lower end of rod O a loop Q is formed and is used as a handle bywhich the rod is worked. T represents the top of the car, as shown inthe different views at Figs. l, 2, and 3.

The ventilator is secured to the top of the car by means of metalstraps, made of iron, brass, tin, or galvanized iron, as fancy maydictate, and by being riveted to the reservoir and screwed to the top ofthe car, as represented at W W, Fig. ,1.

I intend to place four of these ventilators on the top of each car, withthe tubes IVI and L made about eight inches in diameter and placed anequal distance apart. In order to enable the reservoir to be thoroughlycleaned, an opening may be made in the perforated plate and secured witha cover, as represented in Figs. 2 and 4 at M.

When this ventilator is applied t0 use, water is applied to it, and theventilator is filled with water to correspond about with that shown andrepresented at N N, Figs. 2 and 3, and when fresh air is to be admittedinto the car the funnel will stand in the position as represented inFig. l. The air as it passes down into the reservoir will be freed fromany and all particles of dustby its coming in contact with the watercontained in the reservoir, and the natural jarring motion of the carskeeps the water in a continual state of agitation, which prevents anydust from passing through the ventilator into the cars. The current ofair when passing into the cars is shown by the position of t-he darts inFigs. 1 and 2, and when it is desirable to eject foul air from the carthe funnel is reversed by taking hold of the loop Q of rod O and turningit into the position as represented by dotted lines in Fig. 2, when theair will pass from the car, as indicated by the darts also in Fig. 2;and the air in passing to or from the car must pass through the holes bb b b in the perforated plate, Figs. 2 nndwll, as the tube L L and H,and reversible funnel K, when comonly passes through the reservoir,While tube H passes belor the perforated plate, as represented in Fig.2. Funnel K should be turned to correspond with the Way the oars aregoing. Vhat I claim as my invention, and desire to secure by LettersPatent, :ls-

The reservoir I, perforated plate J. tubes bined, constructed, andoperating substantially as described.
